3.2 Commissioning

Before lighting the boiler
• Check the tightness of the gas system & rectify any leaks before continuing.
• Check the correct expansion vessel pressure (1.0 bar with no system pressure).
• Fill the hydraulic system and make sure that all air contained in the boiler and the system has been vented.
• Make sure there are no water leaks in the system, DHW circuits, connections or boiler.
• Make sure there are no flammable liquids or materials near the boiler.
• Check correct connection of the electrical supply and efficiency of the Earth system.
• Make sure the gas valve is adjusted for the gas to be used (see "- THROTTLE position and parameter setting" on
page 22 and fig. 32 on page 22 of cap. 3.1 "Adjustments").
• Fill the trap (see cap. 2.7 "Condensate drain connection").
B
FOR SAFETY REASONS THE AFOREMENTIONED SHOULD BE OBSERVED TO PREVENT AN ESCAPE
OF GAS OR A BUILD-UP OF FUMES WITHIN THE BUILDING. THE POWER SUPPLY MUST BE ISOLAT-
ED BEFORE WORKING ON ANY COMPONENTS WITHIN THE BOILER TO PREVENT ANY RISK OF
ELECTRIC SHOCK.
First boiler ignition
• Ensure there is no demand for hot water or Heating.
• Ensure there is gas and electrical power to the boiler; the display will show the software version number and then
Fh and FH air venting cycle (see cap. 1.3 "Connection to the power supply, switching on and off" on page 5).
• At the end of the FH cycle, the winter mode screen (fig. 8) will appear on the display; Adjust the heating & DHW
outlet temperature settings as required (fig. 12 and fig. 13).
• Top change the Gas type (G20 - G31), check if the relevant parameter is suitable for the type of gas present in the
supply system (""Sc" - Combustion Control Parameters Menu" on page 29 and cap. 3.1 "Adjustments" on page 21).
• Set the boiler to DHW or heating mode (see cap. 1.3 "Connection to the power supply, switching on and off" on
page 5).
• In Heating mode, create a demand: the display shows the "Radiator symbol" and the actual heating system temper-
ature; when the flashing flame symbol appears, the burner is lit and the system is performing the calibration. Wait
for the end of calibration, indicated by the stable flame symbol.
• DHW with hot water demand: the display shows the "Tap symbol" and the actual DHW temperature; when the flash-
ing flame symbol appears, the burner is lit and the system is performing the calibration; wait for the end of the cali-
bration, indicated by the stable flame symbol.
• Carry out the fuel check as described in section 3.1. "Checking the combustion values" on page 22.
• Check that the gas inlet working pressure ahead of the unit complies with the technical data table or as per the reg-
ulations in force at that time.
